Question

Nexus and Nellie's spaceship weighs 1,480 kg. Each bag of wheat weights 38 kg 400 g. There are 50 bags in total. What will be the total weight of spaceship with the bags?

• A. 1,480 kg
• B. 1,920 kg
• C. 3,400 kg

Answer 1

The correct option is C 3,400 kg

Weight of each bag = 38 kg and 400 g

Let's convert the weight into a single unit.

We know, 1,000 g = 1 kg
$\Rightarrow$ 1 g = $\frac{1}{1000}$ kg
$\Rightarrow$ 400 g = $\frac{400}{1000}$ kg = 0.4 kg

$\therefore$ Weight of each bag
= 38 kg + 0.4 kg
= 38.4 kg

Weight of 50 bags
= $50\times 38.4$ kg
= $5\times 10\times \frac{384}{10}$ kg
= $5\times 384$ kg
​​​​​= $1,920$ kg

Weight of the spaceship = 1,480 kg

Total weight of 50 bags and spaceship
$=\text{Weight of 50 bags}+\text{Weight of the spaceship}$
$=1,920\text{kg}+1,480\text{kg}$


$\therefore$ Combined weight is 3,400 kg.
